Cone type venturi integrated valve device
First Claim
1. A cone type venturi integrated valve device comprising:
- a main body having a venturi path which penetrates through the main body in a horizontal direction and a hole which penetrates through the main body from the venturi path to a bottom of the main body, wherein the venturi path includes an inlet, an outlet, a first pressure point at a distance from the inlet, and a second pressure point at a distance from the outlet;
a venturi cone mounted between the first pressure point and the second pressure point in the venturi path of the main body;
a valve path which penetrates through the main body in a vertical direction with respect to the venturi path, the valve path being connected with the first pressure point and the second pressure point of the venturi path; and
valves disposed in the valve path for switching of fluid flowing through the valve path,wherein the venturi cone includes a first cone body having a mild slope surface facing the first pressure point, a second cone body having a steep slope surface facing the second pressure point, and a fixing leg extending from a cone end of the first cone body in the direction of center axis for a predetermined length,wherein the fixing leg is bent downward and a bent end of the fixing leg is inserted into the hole of the main body and attached by welding, andwherein the venturi cone acts to make the pressure of fluid at the second pressure point lower than the pressure of fluid at the first pressure point.

Abstract
A cone type venturi integrated valve device includes a main body, a venturi cone, a valve path, and valves disposed in the valve path. The main body has a venturi path which penetrates though the main body in a horizontal direction and a hole which penetrates through the main body from the venturi path to a bottom of the main body, wherein the venturi path includes an inlet, an outlet, a first pressure point P1 at a distance from the inlet, and a second pressure point P2 at a distance from the outlet. The venturi cone is mounted between the first pressure point P1 and the second pressure point P2 in the venturi path of the main body. The venturi cone has a fixing leg bent downward and a bent end of the fixing leg is inserted into the hole of the main body and attached by welding.
